What is chaga?
{{{TEMP_MARK_{{{TEMP_MARK_238}}}5}}}
At first glance, chaga is not a particularly attractive mushroom. A parasite of birches on which it grows, it takes on a charred wood appearance. Without a stem, it doesn’t have a defined shape: it follows the movement and irregularities of the tree trunk. In forests, it appears as a brown, rounded, dry, and tough mass, which can reach up to 38 cm in width.
In summer and autumn, chaga grows several meters high, directly on the trunks of living trees. It is found mainly on birches although it can also grow on alders, beeches, and other deciduous trees. To parasitize them, our mushroom exploits unhealed injuries. It then sneaks inside the wood and feeds on the tree’s nutrients.
Chaga can withstand extreme climatic conditions including cold (up to -40°C). That’s why it mainly grows in Russia, Canada, Northern Europe, and in the cold regions of Korea and the United States.
{{{TEMP_MARK_2}}}
Once ground and infused, it helped improve digestion, detoxify the body, and support liver and immune system function. Even today, chaga is an integral part of traditional Russian medicine. However, thanks to extensive research and results achieved, its consumption has gradually become popularized throughout the world, where it is considered as a functional mushroom.

🛡 Boosts the immune system
{{{TEMP_MARK_2{{{TEMP_MARK_238}}}}}}
These long sugar molecules are known to stimulate the immune system by promoting the development of leukocytes (or white blood cells) including T-lymphocytes, the body’s natural killer cells. The beta-glucans in chaga also activate interleukin-6 (IL-6), a cytokine that promotes the production of antibodies responsible for detecting and neutralizing pathogens.
It also contains numerous vitamins that strengthen the immune system. It is notably an excellent source of vitamin D (calciferol) which boosts defenses and modulates the immune response. Finally, zinc, copper, and selenium are minerals and trace elements in chaga that contribute to the proper functioning of immunity.

🥝 Source of antioxidants
Chaga has a powerful action against free radicals. Indeed, it is composed of 25% antioxidant actives! Among them are pigments like melanin.
{{{TEMP_MARK_{{{TEMP_MARK_238}}}7}}}
Its antioxidant action is also due to the presence of an enzyme: superoxide dismutase. As an essential component of the free radical elimination mechanism, it has a trapping activity and helps fight against aging. This antioxidant enzyme is also found in reishi (Ganoderma lucidum), a Chinese medicinal mushroom.

♻️ Supports the digestive system
{{{TEMP_MARK_{{{TEMP_MARK_238}}}6}}}
It is also beneficial for the liver and the gallbladder. It particularly promotes the production of bile, essential for digesting food, and protects the liver from lipid oxidation. Furthermore, beta-glucans stimulate good bacteria in the intestines, acting as prebiotics.
This study conducted by various Korean universities on rats shows the hepatoprotective activity of chaga extract.
🔬 Potentially anti-cancer
Chaga is increasingly studied as a potential anti-cancer agent. Indeed, it contains compounds known for their action on unhealthy cells.
By parasitizing birch trees, chaga feeds on the tree’s nutrients such as betulin and betulinic acid. Present in birch sap, these natural substances are cytotoxic, meaning they are toxic to cancer cells.
Moreover, the beta-glucans it contains may help slow the growth of cancer and prevent its spread.
This study conducted by various Korean universities on mice shows how chaga inhibits tumor growth.

How to consume chaga?
In capsules
{{{TEMP_MARK_29}}}
{{{TEMP_MARK_5{{{TEMP_MARK_238}}}}}}
In powder form
{{{TEMP_MARK_4{{{TEMP_MARK_238}}}}}}
The powder can be consumed in infusion or decoction (remember not to boil it), diluted in a drink (hot water, milk, smoothie, latte…) or incorporated into sweet or savory dishes (soups, desserts…).
In mother tincture
{{{TEMP_MARK_{{{TEMP_MARK_238}}}{{{TEMP_MARK_238}}}}}}
The chaga mother tincture is simply diluted in water or fruit juice. However, it has a strong taste that might not appeal to everyone. To soften its woody flavor, you can add honey or maple syrup.

{{{TEMP_MARK_27}}}
Chaga and Chinese medicinal mushrooms
Chaga pairs well with other medicinal mushrooms like reishi, maitake, agaricus blazei, or shiitake. This mushroom synergy, very rich in beta-glucans, has a powerful effect on the immune system.
{{{TEMP_MARK_{{{TEMP_MARK_238}}}9}}}
Sustainable consumption: choose organic chaga
{{{TEMP_MARK_{{{TEMP_MARK_238}}}}}}
Dosage
{{{TEMP_MARK_52}}}
⏳ Chaga can be taken daily or as a 2-week course to support the immune system, prevent ailments, or relieve inflammation.
💊 In tablets: up to 4 per day for 300 mg capsules.
{{{TEMP_MARK_6{{{TEMP_MARK_238}}}}}}
🧪 In tincture: 20 drops, 1 to 3 times a day.
Contraindications and side effects
Chaga has certain contraindications and its consumption is not recommended for the following people:
- As a precaution, young children, pregnant or breastfeeding women should avoid taking it.
- Because it may contain traces of birch, it is not recommended for people allergic to this tree.
- It has certain drug interactions. Thus, it is not recommended for people on anticoagulants, hypoglycemic and immunosuppressive drugs.
- Since chaga affects insulin levels, people with type 1 diabetes or hypoglycemia should avoid consuming it.
- Chaga consumption is not recommended before surgery or in case of coagulation disorders.
Chaga has few side effects. However, at high doses, it can be toxic to the kidneys and promote the occurrence of kidney stones due to its oxalate content.
If you experience side effects, stop your consumption and consult a doctor.
